In 2026, an adolescent boy presented with a 15 cm brownish-red reticulated skin lesion on his abdomen. The condition, known as erythema ab igne, was traced to the daily use of a laptop rested directly on his skin for up to 8 hours.
Why it matters
This case highlights how prolonged, low-grade heat exposure from common consumer electronics can cause significant skin damage. Recognizing the link between device usage patterns and skin changes is essential for timely diagnosis and preventing unnecessary medical investigations.
A clinical report detailed an adolescent patient who developed a 15 cm reticulated skin lesion due to chronic heat exposure. The condition, erythema ab igne, was confirmed after a 2-week investigation that initially suspected a hematoma through x-ray and CT scans.
The details
Erythema ab igne occurs when the skin is repeatedly exposed to moderate heat that is not hot enough to cause an immediate acute burn but is sufficient to damage the underlying capillaries. Over time, this chronic exposure triggers a persistent, net-like pigmentation pattern. The diagnosis is reached by linking clinical observations of the specific lesion pattern to a patient's history of heat exposure, such as resting a device directly on the body.

Health Landscape
Erythema ab igne has long been recognized in medical literature as a skin reaction to consistent, low-grade thermal stress. This case updates the landscape by demonstrating how common personal electronics contribute to the modern spectrum of heat-related skin conditions.
If you notice persistent, brownish-red patterns on your skin in areas that frequently contact laptops or tablets, consider the possibility of chronic heat exposure. Discuss these skin changes with your doctor to rule out other dermatological conditions and identify potential sources of heat in your daily routine.
The takeaway
The primary insight is that even low-grade heat sources can cause visible skin damage if the contact is frequent and sustained. As a practical habit, avoid resting electronics directly on your skin for extended periods by using a desk or a protective barrier, such as a laptop cooling pad.
